Answer:
Step-by-step explanation:
Given is a scatter plot and the regression line using least squares.
We are required to find out how many more goals a player will score for every additional hour of practice.
In other words, we are to find the slope of the regression line.
By taking two points on the line we can find slope of the line.
(1.5,2) and (6.5,6) are points on the line
Find slope using two point formula
Slope =
near slope is 3/4
Hence answer is option b.

Answer:
The new crew and the experience crew working together can paint the apartment in 4 hours.
Step-by-step explanation:
Given:
Time taken by new crew of painters to paint an apartment = 12 hours
Time taken by experience crew of painters to paint an apartment = 6 hours
To find the time taken by them to paint the apartment working together.
Solution:
Using unitary method to determine their 1 hour work.
In 12 hours the new crew can paint = 1 apartment
So,in 1 hours the new crew can paint = of the apartment
In 6 hours the experience crew can paint = 1 apartment
So,in 1 hour the experience crew can paint = of the apartment
Now, the new crew and the experience crew are working together.
So, in 1 hour, they can paint :
⇒
Taking LCD = 12, we will add fraction.
⇒
⇒
Simplifying fraction we have:
⇒ of an apartment
Again using unitary method to determine the time taken by them working together to paint the whole apartment.
They can paint of an apartment in 1 hour.
To paint 1 apartment they will take = hours
Thus, the new crew and the experience crew working together can paint the apartment in 4 hours.
